Answer 2

Explanation:

$\huge{\underline{\mathfrak{\red{A}\pink{n}\green{s}\blue{w}\purple{e}\orange{r}}}}$

So, as you have stated, red light has a lower index of refraction than blue light since it also has a shorter wavelength, so lower index of refraction corresponds to higher speed in a material. n2=1.51 for red light and θ2=13.09 degrees, n2=1.53 for blue light, and θ2=12.91 degrees.
